Three people in South Carolina are among the 100 who have been sickened by a Salmonella outbreak that has hit 19 states and the District of Columbia.

At least one of the confirmed case patients in South Carolina, reported eating sushi purchased from a grocery store before becoming ill. Although many patients in other states also reported eating foods made with raw fish, that they had purchased at grocery stores and restaurants, a definite source of the outbreak has not yet been determined.

South Carolina officials are working with investigators from the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) on traceback efforts to find the source of the outbreak.

Case patients in South Carolina are from Greenville, Newberry and Pickens counties. None of them was hospitalized.

Salmonella poisoning can be serious and have long-term health effects. Health officials advise anyone with symptoms of Salmonella poisoning to contact a health care provider.
